Abstract
Peltogaster cunatus is reported from Norwegian waters for the first time. The percentage of infection was 5.5 on Pagurus cuanensis and 0.9 on Pagurus prideauxi. A brief account is given of the size of the parasites and the hosts, and of the distribution of P. curvatus. A new synonym of Pagurus prideauxi is noted: Cancer bernhardus Ström 1788 (non Cancer bemhardus L.).
